Design and optimisation of CMOS wideband amplifiers
Several CMOS amplifier types are compared and optimized for high-frequency applications. Scaling laws are derived for the power consumption as a function of the gain bandwidth, the load capacitance and the second pole. It is shown that minor modifications on existing circuits can save over a factor of two of power consumption. A 3-μm wideband amplifier is presented with 150-MHz gain-bandwidth and 60° phase margin and with 30 mW of power consumption for a load capacitance of 2 pF
